LAWN-SPRINKLER.

I SPECIFICATION forming part of Letters Patent No. 483,017, datedSeptember 20, 1892. Application filed November 80,1891. Serial No.413,659. (No model.)

To all whom it may concern:

Be it known that I, NICHOLAS L. RIGBY, a citizen of the United States,and a resident of Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inLawn-Sprinklers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a top plan view. Fig. 2 is avertical sectionof nozzle and coupling, and Fig. 3 is a detail view.

This invention has relation to certain new and useful improvements insprinkler attachments for hose-pipes; and it consists in the novelconstruction and combination of parts, as hereinafter specified, andpointed out in the claims.

In the accompanying drawings, the letter A designates a nozzle pipe ortube, preferably of metal, having acoupling a for attachment to ahose-pipe and shown as bent into approximately 0 shape, terminating atits free end in an inwardly-turned arm I), having an elbow-coupling B,to which the nozzle is connected. The position of the nozzle is shown asabout centrally between the arms of the bend and standing at rightangles to the plane thereof.

The nozzle 0 comprises the case or shell 0, having a straight cylindricbore and externally threaded at one end for engagement with the couplingB. In this shell or casing is a plug G, which consists of astem or shankexactly centrally therein and having at its inner end a series of radialflanges g, separated from each other by the tapered grooves or channelsf. Above these flanges the shank is gradually enlarged or tapered,terminating in a flange or head h, forming an angular shoulder thereon.The flanges or wings g fit closely in the bore of the shell and havesufficient frictional contact therewith to prevent them from beingforced out of the nozzle -that is to say, the radial spread of the wingsor flanges is only slightly less than the diameter of the interior boreof the nozzle, into which they are driven with considerable force. Bythe application, however, of a suitable tool the plug may be adjusted inthe nozzle so as to regulate the discharge. By reason of this close fitof the wings or flanges it will be apparent that it will be impossiblefor the plug or stem to get out of center as it is moved up or down inthe shell, thus insuring an even discharge at all points. The wateradmitted between the wings or flanges is discharged around the shank,and, striking against the shoulder formed by the head It, 1s broken upinto a fine spray, which is thrown evenly to all sides, and not in asingle rlng, several feet distant from the nozzle.

It will be observed that the bend given the pipe, which may be of anysuitable shape, forms a base or support for the sprinkler, holding it inupright position. By pulling on the hose or on a cord attached to thesprinkler it may be moved from place to place without necessitating thecutting ofi of the water in order to approach it and move it by thehand.

The case or shell 0 is usually provided with a wrench-seat c.

Having thus fully described my inventlon, whatIbelieve to be new, anddesire to secure by Letters Patent, is

1. The herein-described nozzle, comprising the casing or shell having asmooth interior bore and the plug adjustably arranged 1n said bore, saidplug comprising a shank por- 8 5 tion projecting beyond the upper end ofthe shell and terminating in a head or flange, said shank being taperedinwardly and having at its lower portion a series of radial verticalwings or flanges separated from each 0 other by tapered grooves orchannels, substantially as specified.

2. The combination, with the pipe base or support having theelbow-coupling B, of the casing or shell having a threaded engage- 5ment- With said socket and formed with a smooth interior bore, and aplug adj ustably arranged in said bore, said plug comprlsing Intestimony whereof I affix my signature in presence of two witnesses.
